An Alouette is a type of bird. In English it's a lark. This song is a very popular French song. I bet your parents even learned it in school. Unfortunately, it's not a very kind song. Translated it means: Lark, nice/sweet lark, lark, I'm going to pull your feathers out. I'll pull the feathers out of your head, your beak, your back, your feet, your wings.
